Task switcher on Lubuntu 20.04 showing all tasks instead of task from current workspace

I am using Lubuntu 20.04.03 LTS (Ubuntu + LXQT, bassically), fresh install. I can configure Task Manager to show only windows from current desktop (workspace), but the task switcher still shows windows from all desktops. Is there a way I can synchronize both? Before upgrading (18.04) behaviour was as expected.

Thanks in advance.

Solution 1:

I found the solution for my problem. In the keys binding configuration file (now in ~/.config/openbox/lxqt-rc.xml) the combination config for switching between windows is A-Tab. That's right, but there's also an option called <allDesktops>. In my case it said yes, I changed it to no and now it shows only windows from the current desktop.

Solution 2:

Right-click on the panel. First option in Task Manager Settings is Show only windows from desktop.
